Nemesia plant named ‘Nesplupurwhi’

ABSTRACT

A new cultivar of  Nemesia  plant named ‘Nesplupurwhi’ that is characterized by good high temperature tolerance, white flowers, profuse flowering and a semi-trailing habit.

Botanical classification: Nemesia hybrida.

Variety denomination: ‘Nesplupurwhi’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Nemesia plant botanically known as Nemesia hybrida and hereinafter referred to by the cultivar name ‘Nesplupurwhi’.

The new Nemesia is the product of a planned breeding program conducted by the inventor in Gensingen, Germany. The objective of the breeding program is to create new Nemesia cultivars with unique flower colors and improved high temperature tolerance.

‘Nesplupurwhi’ is a hybrid that originated from a crossing in the Summer of 2003 of the female or seed parent a proprietary Nemesia identified as Neb Reinweiss II (not patented) and the male or pollen parent a proprietary Nemesia identified as White Dream I tet 7 (not patented). The resulting seeds were subsequently planted and grown. The cultivar ‘Nesplupurwhi’ was selected by the inventor in the Spring of 2004 as a single plant within the progeny of the stated cross in Gensingen, Germany.

Asexual reproduction of the new cultivar ‘Nesplupurwhi’ first occurred by terminal cuttings in July of 2004 in Gensingen, Germany. Since that time, under careful observation, the unique characteristics of the new cultivar have been uniform, stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

The following represent the distinguishing characteristics of the new Nemesia cultivar ‘Nesplupurwhi’. These traits in combination distinguish ‘Nesplupurwhi’ as a new and distinct cultivar apart from other existing known varieties of Nemesia.

-   -   1. Nemesia ‘Nesplupurwhi’ exhibits good high temperature         tolerance.     -   2. Nemesia ‘Nesplupurwhi’ exhibits white flowers with a yellow         palate.     -   3. Nemesia ‘Nesplupurwhi’ exhibits profuse continuous flowering.     -   4. Nemesia ‘Nesplupurwhi’ exhibits a semi-trailing habit.

The closest comparison cultivars are Nemesia ‘Nesplugoyel’ (U.S. Plant patent application Ser. No. 12/927,998) and Nemesia ‘Inntraiwhi’ (not patented).

‘Nesplupurwhi’ is distinguishable from Nemesia ‘Nesplugoyel’ by the following characteristics:

-   -   1. ‘Nesplupurwhi’ has white flowers. The flowers of         ‘Nesplugoyel’ are yellow. ‘Nesplupurwhi’ is distinguishable from         ‘Inntraiwhi’ by the following characteristics:     -   1. ‘Nesplupurwhi’ exhibits a less trailing habit.     -   2. ‘Nesplupurwhi’ has larger flowers than ‘Inntraiwhi’.     -   3. ‘Nesplupurwhi’ has lighter white flowers than ‘Inntraiwhi’.     -   4. ‘Nesplupurwhi’ has better high temperature tolerance than         ‘Inntraiwhi’.

‘Nesplupurwhi’ is distinguishable from the female or seed parent Nemesia Neb Reinweiss II by the following characteristics:

-   -   1. ‘Nesplupurwhi’ has smaller flowers.     -   2. ‘Nesplupurwhi’ has smaller leaves.     -   3. ‘Nesplupurwhi’ has a semi-trailing habit. Neb Reinweiss II         has an upright habit.     -   4. ‘Nesplupurwhi’ has better high temperature tolerance.

‘Nesplupurwhi’ is distinguishable from the male or pollen parent Nemesia White Dream I tet 7 by the following characteristics:

-   -   1. ‘Nesplupurwhi’ has lighter white flowers.     -   2. ‘Nesplupurwhi’ exhibits a larger number of branches.     -   3. ‘Nesplupurwhi’ exhibits more vigorous growth.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying photograph illustrates the distinguishing traits of Nemesia ‘Nesplupurwhi’. The plant in the photograph shows an overall view of a 20 week old plant. The photograph was taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.

BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of the new Nemesia cultivar named ‘Nesplupurwhi’. Data was collected in Gensingen, Germany from 20 week old glass greenhouse grown plants in 12 cm. diameter containers. The time of year was Summer and the temperature range was 16-35 degrees Centigrade during the day and 12-16 degrees Centigrade at night. The light level was natural light. No photoperiodic treatments or growth retardants were used. Color determinations are in accordance with The Royal Horticultural Society Colour Chart 2007 edition, except where general color terms of ordinary dictionary significance are used. The growing requirements are similar to the species. ‘Nesplupurwhi’ has not been tested under all possible conditions and phenotypic differences may be observed with variations in environmental, climatic, and cultural conditions, however, without any variance in genotype.
